It leads to problems and to foolishness like juice-squeezing hydraulic presses for the home, but I feel like that wackiness pays for itself when it has brilliant people asking 'what does life look like when we have solar powered robots and replicators giving us all important things for essentially free?'

That may produce activists… I don't think you'd call them 'accelerationist' activists. That term is akin to posadism and implies it's activists secretly trying to worsen conditions in hopes of stoking an eventual revolution. SV does have plenty of those, many of 'em leading companies, but in general techno-utopianism wouldn't be characterized as accelerationist.
